So am I correct in assuming that the A1400-8 and the A1400-2 are essentially the same amps with the -2 only sharing up to peak 1400 watts across 2 channels (700 max for 2 channels) where as the -8 shares the peak 1400 watts across 8 channels. If the -8 is only utilizing 2 channel stereo (i.e. for music) 700 watts would be available per 2 channels as with the true 2 channel -2....is that correct?
